Re: How to compute SPL from sound inputed from a microphone.

Congratulations :) I think that it would be worth shifting this topic to the Nyquist board - OK with you or would you prefer to leave it here for now? The two topics could possibly be merged, though I'm not sure if the design goals of the plug-ins are quite the same, so it may be better to keep them...

Re: "Wave Stats" plug-in

Thanks endolith. Testing both your version and this one, the results are pretty good. Checking sine waves against the on-line calculator on this page http://www.diracdelta.co.uk/science/source/a/w/aweighting/source.html In the mid-range the A-weighted values match extremely closely (within 0.1 dB) A...

Re: No 'Export as MP3' button in Audacity 1.3.12-beta (Unico

... at times I get an error saying that these types of files usually have an mp3 extension and asking me if I really want to export as is (without the mp3 extension) That will happen if the file name includes a dot. For example if you have a file name "badaz-boogie feat. MC Jabber" then A...

Re: Mix multi-channel track to mono

Or a more "exotic" way of doing the same thing: (defun mix (s-in) (if (arrayp s-in) (let ((c 0)(n (/ 1.0(length s-in)))) (multichan-expand #'(lambda (x) (if (= c 0)(setq c 1)(setf (aref s-in 0)(sum(aref s-in 0)x)))) s-in) (scale n (aref s-in 0))) s-in)) (mix s) An interesting thing (that a...

Re: Amplify settings (2) are always locked together

I am not using wav files at all. Just .aup and .flac . In case it's not been mentioned before in this long topic, FLAC supports ReplayGain http://wiki.hydrogenaudio.org/index.php?title=Replay_Gain On another issue, I really would like to know why ... I've no idea about that one, but I think Gale re...

Re: New Plug-In: big G

Re: Measuring Hz and dB of a song

You can get frequency data from the "Plot Spectrum" tool in the "Analyze" menu. This tool has been significantly improved in the 1.3.12 version of Audacity. Also, I've just posted an amplitude analysis plug-in here that may be useful: http://forum.audacityteam.org/viewtopic.php?f...
